Many people at work have apparently responded to the “get vaccinated or get tested” announcement by refusing to wear any kind of face covering at all. I actually asked my manager this morning if the corporate face covering policy was still in place; he said it was, and then added that he hasn’t seen any studies showing that it does any good. 
On the plus side, an employee was injured today badly enough that they needed medical attention, and someone actually called an ambulance instead of just stuffing the victim into the car of a designated “first responder” (defined here as an employee who took a first aid course).
